OPERATING MECHANISM FOR MAGNE'I'OS.

No. 880,974. Original application filed April 20, 1906,

To all whom it may concern:

Be it known-that I, ALBERT N. CLASSON, a citizen of the United States, and a resident of'Rutland townshi in the county pfLasails and State of linoi's, have inventeda new .andlmproved Operating Mechanism for Magnetos, of which the following is a full, clear, and exact description. ments in electrical igniting apparatus or internal combustion engines, ticularly to the mechanism magneto h the engine, and continuously 1n the same irection irrespective of the direc tion of rotation of the engine. In starting an engine it is often necessaryto give the crank shaft a few turns in the reverse direction but this ordinarily involves a rotation of the magneto also in the reverse direction. In my improved construction the magneto may be rotated in the desired direction while the engine is being reversed, and assoon as the engine starts its normal'direction of rotaautomatically operates to continue the rotation of the magneto in the same direction as before.

Reference is tobe had to the accompanying drawings, formin a part of this specification, in which simi a1 characters ence indicate corres ondingparts in all the figures, and in whic I Fi re 1 is a front elevation of a conventiona internal combustion engine showing my invention a plied thereto, ing the parts in tile positions the the engine is being reversed larged elevation similar to a 1, but showing the parts in t e position 00- cupied durin the normal running of the machine; and operating mcc iamsm.

My improved operating mechanism 1S adapted for use in connection with any type occupy when 1g. 2 IS an enof internal combustion engine for operatingthe magneto of the igniting system, an d also adapted for use m operating other vices thanmagnetos. I

The s ecific mechanism illustrated is that y disclosed in my application, Serial revious o. 312,800, filed A ril 20, 1906, of which this application is a ivision.

The 0 erating' mechanism is mounted adjacent t 1e engine or upon the engine frame and serves to transmit motion from the fl wheel 10 of the engine to the armature sha t Specification of Letters Patent.

Adyacent the ily wheel there is'imounted an arm 12 pivoted at one end-and having a pulley 13 pivoted thereon same lane as the drive Abe t 14 engages with wheel of the engine.

a pulley 15 on the magthis pulley and with neto armature shaft, and the arm 12 is normally so disposed that this belt frictionally engages with the periphery of the drive wheel to be operated by' 'the latter. The belt is held against thedrive wheel withthe desired amount of pressure by the action of a spring 16 engaging with the arm 12 and tending to move thelatter "toward the drive wheel. Pivoted on the arm 12 is a second ar1n17 carrying a belt-tightening pulley 18 held in engagement with the belt by a coil spring 19. Thus, the arm 12 maybe moved upon. its

pivot withoutloosening-the belt or varying the-tension thereof.

Pivoted to the arm 12, adjacent its outer end, I provide an extension arm 20 hearing a roller 21 lying in the same plane as the pulley 13. The arm 20 is ivoted above the center of the ulley and 18 of such a length that when sai arm extends in the same general direction as the arm 12, the pulley 1.3

. and roller 21 will vbe spaced apart as shown in Fi 2, but when the arm 20 is moved to a position substantially at right angles to the arm 12, the roller 21. will engage with the outer. surface of the belt and with the engine fly wheel 10 intermediate said drive wheel and the pulley 13, as shown in Fig. 1. The

20 is limited by suit 23, so that the arm cannot 1 swing to the right from the position shown in movement of the arm able stops 22 and Fig. 2 and cannot descend to a lower posi tion than that shown in Fig. 1.

In the operation of my improved mechanism the parts normally occupy the positions shown in Fig. 2, and the fly wheel 10 and the belt 14 travel in the directions indicated by the arrows, and the magneto is continuously rotated in one direction. Should the arm 20 accidentally fall to the position illustrated in Fig. 1, the upward movement of the adjacent surface of the fly wheel will keep the roller 21 from interfering with the frictional engagement of the belt 14 and the fly wheel. If it is desirable to rotate the engine In tple operation thereof, the arm 20 is lowered. to the position shown in Fig. 1; the roller 21 wedges between the flywheel and the pulley 13 and acts as an idler to cause them both to, rotate in the same direction.v The down:

ward movement of the adjacent surface of tion engine, an ignition system therefor in eluding a magneto, gearing for driving said magneto, and an intermediate gear member cap'ableof being set in action as a part of said gearing to continue the normal operation of the magneto u on the reversal of the engine.

2. The com ination of a rotatable memher, a magneto, gearing for rotating said magneto from said member, and an intermediate gear member movable into position to form I a part of said gearing and automatically mov- 'able out of operation upon a change in the direction of rotation of the member.
